## Class ImplicitResultChecker

- java.lang.Object
- - net.sf.saxon.event.SequenceReceiver
  - - net.sf.saxon.event.ProxyReceiver
    - - net.sf.saxon.serialize.ImplicitResultChecker

- All Implemented Interfaces:
    Result, Receiver

      public class ImplicitResultChecker
      extends ProxyReceiver

  This filter is inserted into the serializer pipeline when serializing an implicit XSLT result tree, that is, one that is created without use of xsl:result-document. Its main purpose is to check, if and only if the result destination is actually written to, that it does not conflict with an explicit result destination with the same URI. It also ensures that the output destination is opened before it is first written to.
